[0002] Traditional pull-tab aluminum formwork removal tools are used in combination of two types: one is a long-handled pull-tab remover to remove the pull-tabs at the top of the wall, and the other is a knocking hammer to remove the pull-tabs in the middle and lower parts of the wall. For such pull-tab aluminum formwork demoulding, first use an ordinary flat-head hammer to knock and remove the pull-tabs on the middle and lower parts of the wall, and replace the ends of the pull-tabs on the upper wall with flat steel pipes for cleaning. This cleaning method is inefficient and requires repeated tool changes during the process; and when the flat-head hammer knocks the pull-tab, the hammering position is offset to the left and right, which will cause the pull-tab to shift to the left and right, making it difficult to knock it off. At the same time, it will also cause the concrete on both sides of the pull-tab position to be squeezed and fall off, creating a quality perception risk; and the pull-tab fragments that fall to the ground after knocking are not collected, but are treated as construction waste, which is not conducive to environmental protection and resource recycling.

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Reference Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application discloses a reusable aluminum mold pull tab and a matching removal device.

[0021] Its aluminum mold pull tabs include: The pull-tab middle part 1 and two pull-tab end parts 2 are arranged at both ends thereof. A locking structure is arranged between the pull-tab end parts 2 and the pull-tab middle part 1 for realizing locking / unlocking after the two are rotated to a set angle. The pull-tab end parts 2 are provided with a pin hole 21.

[0022] Specifically, the locking structure includes: The connecting buckle 22 includes a connecting portion 221 and a buckle portion 222. The connecting portion 221 is fixed to the pull-tab end portion 2. The buckle portion 222 is wider than the connecting portion 221. The buckle portion 222 is vertically arranged with the connecting buckle 22, so that the pull-tab end portion 2 can be locked / unlocked after being rotated 90° relative to the pull-tab middle portion 1. There are two buckle tubes 11, which are fixed to the two ends of the pull tab middle part 1 respectively, and the inner diameter of the buckle tube 11 is not less than the width of the buckle part 222; The limiting cylinder 12 is fixedly connected to the hollow part of the end of the buckle cylinder 11 away from the middle part 1 of the pull tab. The limiting cylinder 12 is provided with a transverse groove 121 for the buckle part 222 to be inserted into the hollow part of the buckle cylinder 11. The axial length of the limiting cylinder 12 along the buckle cylinder 11 is not less than the length of the connecting part 221. The inner diameter of the limiting cylinder 12 is not less than the width of the connecting part 221 and is not greater than the width of the buckle part 222. When the pull-tab end portion 2 is rotated to be flush with the pull-tab middle portion 1 , the buckle portion 222 does not correspond to the transverse groove 121 .

[0023] Reference Figure 4 , Figure 5 and Figure 6 , the removal device includes: The removal rod 3 has two ends connected and a cavity is provided inside; A collection box 41 is used to collect the removed pull-tab ends 2. When specifically configured, a detachable inner container is provided inside the box. When the pull-tab ends 2 in the inner container are fully collected, the inner container can be taken out for transfer. A hose 42 for connecting the removal rod 3 and the collection box 41; A fixing pin 51 is fixed in the cavity of the removal rod 3; The movable pin 52 has a gap between it and the fixed pin 51 for the pull-tab end 2 to extend into, and is plugged and adapted to the pin hole 21; and The control mechanism is used to drive the movable pin 52 to approach the fixed pin 51 and lock the pin hole 21 on the pull-tab end 2 extending into the cavity of the removal rod 3.

[0024] Therefore, by setting the aluminum mold pull tab into a pull tab middle part 1 and two pull tab ends 2, and realizing a simple snap-on connection between the pull tab ends 2 and the pull tab middle part 1 through the cooperation of the buckle tube 11 and the connecting buckle 22, a convenient and detachable connection between the pull tab ends 2 and the pull tab middle part 1 can be achieved, so that after the aluminum mold pull tab is used, the pull tab ends 2 can be recycled and reused, which can effectively improve the efficiency of the aluminum mold pull tab dismantling construction, and reduce the material loss rate by reusing the pull tab ends 2.

[0025] By configuring the dismantling device to be a dismantling rod 3 plus a collecting box 41, when the construction personnel dismantle the pull-tab end 2, they only need to align the head end of the dismantling rod 3 with the pull-tab end 2, so that the pull-tab end 2 is embedded in the cavity of the dismantling rod 3 and the movable pin 52 in the dismantling rod 3 is aligned with the latch hole 21 on the pull-tab end 2, and then the movable pin 52 is driven through the latch hole 21 and pressed against the fixed pin 51 by the control mechanism; at this time, the pull-tab end 2 is confined in the cavity of the dismantling rod 3, and the dismantling rod 3 can be driven to rotate on the pull-tab middle part 1 by rotating the dismantling rod 3, so that the buckle part 222 is aligned with the transverse groove 121 on the limiting tube 12, and then the dismantling rod 3 is pulled to make the connecting buckle 22 disengage from the buckle tube 11, so that the dismantling of the pull-tab end 2 on the pull-tab middle part 1 can be completed, making the dismantling process of the pull-tab end 2 simple and efficient.

[0026] Then, the movable pin 52 is driven out of the pin hole 21 through the control mechanism. At this time, the pull-tab end 2 is released from the restriction. It only needs to lift the head end of the removal rod 3. The removed pull-tab end 2 can enter the hose 42 along the cavity in the removal rod 3 and finally be transported to the collection box 41 for collection. The disassembly, transmission and collection processes of the aluminum mold pull-tabs are integrated into a construction process, which effectively reduces environmental pollution during the construction process, avoids secondary cleaning, and reduces labor costs. Moreover, completing the construction process at one time can effectively improve the construction progress and greatly save the construction period.

[0027] Specifically, to facilitate the construction personnel to operate, refer to Figure 4 , Figure 5 and Figure 6 , the control mechanism comprises: The movable rod 61 is located in the cavity of the removal rod 3 and one end of the movable rod is fixedly connected to the movable pin 52. The control rod 62 is fixedly connected to the movable rod 61. The connecting portion 221 of the control rod 62 and the movable rod 61 is hinged in the removal rod 3, and the hinge axis of the two is orthogonal to the axis of the movable pin 52. A button 63 is provided at one end of the removal rod 3 close to the hose 42 and connected to the control rod 62. When the button 63 is pressed, the control rod 62 is driven to rotate in the removal rod 3 so that the movable pin 52 is close to the fixed pin 51. The short rod is used to connect the button 63 and the control rod 62. A return spring (not shown in the figure) is disposed on the outer sleeve of the short rod. One end of the return spring is pressed against the button 63, and the other end is pressed against the removal rod 3.

[0028] Moreover, a fork block 7 is fixedly connected to one end of the movable rod 61 close to the control rod 62, and the fork width of the fork block 7 is not less than the thickness of the pull-tab end 2; when the pull-tab end 2 entering the cavity of the removal rod 3 is embedded in the fork of the fork block 7, the movable pin 52 is aligned with the pin hole 21.

[0029] Furthermore, a baffle plate 8 is fixedly connected to the cavity of the removal rod 3, and a positioning groove 81 is formed in the middle of the baffle plate 8 for the pull-tab end 2 to pass through, the positioning groove 81 corresponds to the fork of the fork block 7, and the width of the positioning groove 81 is greater than the thickness of the pull-tab end 2. The fixed pin 51 and the movable pin 52 are both located on the side of the baffle plate 8 away from the hose 42, and the fixed pin 51 is fixed to the baffle plate 8.

[0030] The end of the removal rod 3 facing away from the hose 42 is fixedly connected to a sealing plate 9, and a positioning hole 91 is penetrated through the sealing plate 9. When the pull-tab end 2 entering the cavity of the removal rod 3 is embedded in the fork of the fork block 7 and fits against the lower hole wall of the positioning hole 91, the movable pin 52 is completely aligned with the pin hole 21.

[0031] Therefore, when the construction personnel hold the dismantling rod 3 and put its head end on the pull-tab end 2, the pull-tab end 2 first passes through the positioning hole 91 on the sealing plate 9, which can limit the position of the pull-tab end 2 in the vertical direction to a certain extent; then the pull-tab end 2 passes through the positioning groove 81 on the baffle 8, which can limit the lateral shaking amount of the pull-tab end 2 in the horizontal plane to a certain extent; and when the head end of the pull-tab end 2 is pressed against the fork of the fork block 7 on the movable rod 61, the pull-tab end 2 can be limited in the depth direction of the horizontal plane. At this time, after the restriction or positioning in three directions, the pin hole 21 on the pull-tab end 2 can be accurately aligned with the movable pin 52, ensuring that when the construction personnel press the pull-tab end 2 with the dismantling rod 3, the pull-tab end 2 can be locked, without the need for complicated positioning and calibration operations, greatly improving the operating efficiency.

[0032] When continuing the operation, it is only necessary to press the button 63, the reset spring is compressed, and the button 63 pushes the control rod 62 to swing in the removal rod 3 through the short rod, so that the movable pin 52 on the movable rod 61 moves in the direction close to the fixed pin 51 and passes through the pin hole 21 on the pull-tab end 2. At this time, the pull-tab end 2 is stably locked, and the removal rod 3 can be rotated to remove the pull-tab end 2; after the removal is completed, release the button 63, and the button 63 pulls the control rod 62 through the short rod under the deformation force of the reset spring to swing in the opposite direction, so that the movable pin 52 is away from the fixed pin 51, and the operator then shakes the head end of the removal rod 3 horizontally and raises the head end, so that the pull-tab end 2 escapes from the fork of the fork block 7, and completely slides into the cavity of the removal rod 3 in the gap on the side of the fork block 7 away from the movable rod 61, so as to complete the collection of the pull-tab end 2 after removal.

[0033] In addition, refer to Figure 4 and Figure 5 The end of the dismantling rod 3 close to the hose 42 is provided with a bent holding portion 31, and the button 63 is provided at the holding portion 31. With the setting of the bent holding portion 31, the construction workers can dismantle the pull-tab end 2 at a higher position on the wall column while standing on the ground, which is more practical.

[0034] The present application also discloses a method for removing a reusable aluminum mold pull tab. Based on the above-mentioned reusable aluminum mold pull tab and the matching removal device, the following technical solution is adopted: A method for removing a reusable aluminum mold pull tab comprises the following steps: S1. After the aluminum formwork is removed and the concrete pouring of the main structure wall column is completed, the aluminum formwork is removed after reaching the set strength so that the pull tab end 2 is exposed outside the wall column; S2. Remove the pull tab, hold the removal rod 3 so that the pull tab end 2 is inserted into the cavity of the removal rod 3, and after the movable pin 52 is aligned with the latch hole 21 on the pull tab end 2, the movable pin 52 is controlled by the control mechanism to pass through the latch hole 21 and abut against the fixed pin 51, and the removal rod 3 is rotated to unlock the pull tab end 2 and the pull tab end 2 with the help of the locking structure, and then the pull tab end 2 is pulled out from the pull tab middle 1; S3. Pull tab collection, lift the head end of the removal rod 3, and release the movable pin 52, so that the removed pull tab end 2 slides along the removal rod 3 cavity and the hose 42 to the collection box 41; S4. Cleaning of the pull tab: after the collection box 41 is full, the pull tab end 2 is transferred for next use.

[0035] The implementation principle of a reusable aluminum mold pull tab in the embodiment of the present application is: By configuring the aluminum mold pull tab to be a pull tab middle portion 1 and two pull tab ends 2, and realizing a simple snap-on connection between the pull tab ends 2 and the pull tab middle portion 1 through the cooperation of the buckle tube 11 and the connecting buckle 22, a convenient and detachable connection between the pull tab ends 2 and the pull tab middle portion 1 can be realized, so that after the aluminum mold pull tab is used up, the pull tab ends 2 can be recycled and reused, which can effectively improve the efficiency of the aluminum mold pull tab dismantling construction, and reduce the material loss rate by reusing the pull tab ends 2.

[0036] By configuring the dismantling device to be a dismantling rod 3 plus a collecting box 41, when the construction personnel are removing the pull-tab end 2, they only need to align the head end of the dismantling rod 3 with the pull-tab end 2, so that the pull-tab end 2 is embedded in the cavity of the dismantling rod 3 and the movable pin 52 in the dismantling rod 3 is aligned with the latch hole 21 on the pull-tab end 2, and then press the button 63 to make the control rod 62 drive the movable rod 61 to swing so as to drive the movable pin 52 to pass through the latch hole 21 and abut against the fixed pin 51; at this time, the pull-tab end 2 is confined in the cavity of the dismantling rod 3, and it is only necessary to rotate the dismantling rod 3 to drive the pull-tab end 2 to rotate on the pull-tab middle part 1, and then align the buckle part 222 with the transverse groove 121 on the limiting tube 12, and then pull the dismantling rod 3 to make the connecting buckle 22 disengage from the buckle tube 11, so that the dismantling of the pull-tab end 2 on the pull-tab middle part 1 can be completed, making the dismantling process of the pull-tab end 2 simple and efficient.

[0037] Then, the reset spring drives the button 63 to drive the control rod 62 to swing in the opposite direction to drive the movable pin 52 to disengage from the pin hole 21. At this time, the pull-tab end 2 is released from the restriction. It only needs to lift and shake the head end of the removal rod 3, and the removed pull-tab end 2 can enter the hose 42 along the cavity in the removal rod 3 and finally be transported to the collection box 41 for collection; thereby, the disassembly, transmission and collection processes of the aluminum mold pull-tab are integrated into a construction process, which can effectively reduce environmental pollution during the construction process, avoid secondary cleaning, and reduce labor costs; and by completing the construction process at one time, the construction progress can be effectively improved, greatly saving the construction period.
